My dentist just wants to just fill the holes left by root canal through bridge. Please advise.

Thanks for your question... If there was decay under the bridge then most certainly it would have to be removed and redone, there is no way to just fill the holes or remove the bridge and reuse it again.  The bridge has to be sectioned off, decay removed, teeth rebuilt and a new bridge fabricated.  Good luck

Hi:Very good question.  If there is decay under the bridge you are about removing the bridge to get all of the decay out.  However, most likely you can not remove the cemented brdige and recement it with significant damage to the bridge.  You most likely need a new bridge.Best.Dr. Maddahi

Once teeth that support the bridge have been affected by the decay and already cause the complications such as tooth abscess for which you had to have a root canal treatment it usually a straight indication for a bridge removal AND replacement. To remove the fixed bridge especially if it's a long span one may require cutting through it's strictures which in turn makes it impossible to re-use. On the other hand the supporting teeth may have changed due to a decay process and therefore no longer fit the bridge restoration as precisely as they should. All this validate the new bridge restoration upon the control and elimination of any problems with supporting teeth. Another good option is to consider dental implants to avoid future problems that are usually associated with long span bridge structures. When the decay has been detected under the current bridge and it cannot be fully removed then simply closing the holes is not enough. Hope this helped. Good luck, Dr. Daniyar  

Unfortunately, the bridge most probably cannot be removed and put back. If the bridge is removed in order to repair the decayed tooth, you'll need a new bridge made for that area. It may be possible to remove the decay in that tooth first, then build up in the inside to stabilize it. Your dentist will need to do something other than just filling in the hole made in the bridge.
